Viking Wall Oven Repair in Toronto — Broiler not working

• The first split on a Viking broiler-not-working call is gas vs electric, because Viking pro ovens broil two completely different ways and the parts do not cross. On a GAS oven (VGIC/VGSC/VGSS/VGSO) the broiler is fired by the flat hot-surface glow-bar igniter 065650-000 (Viking's current sub from PB040001; also 792263 / AP5315579 / SGR40001), and the same igniter style serves bake, broil AND griddle. As the silicon-carbide bar ages it goes resistive: it still glows orange but its current falls below the roughly 3.2-3.6A it must pull to flex the gas-valve bimetal open, so the broiler glows and never lights. The honest test is amp draw, not the glow - we clamp the igniter while it glows and apply the standard 90-second glow-and-no-light rule: an igniter that glows more than ~90 seconds without lighting the broil burner is too weak and is replaced. We never quote a bake part for a gas-broil no-light; the broil path is the 065650-000 igniter feeding the broil side of the valve.
• The most-missed gas-broiler fault on a Viking is a clogged broil-burner orifice, and it is the one that survives a parts-cannon. We have seen the VGIC pattern documented on Viking service forums: the broiler stays dead even with the igniter confirmed drawing a healthy ~3.6A and the gas safety valve testing good for continuity, because a speck of grease or carbon has plugged the broil-burner orifice and no gas reaches the flame. Viking's own venting routes oven heat past the broil tube, so grease and particulate deposit on that orifice over years of use - this is a maintenance fault, not an electrical one. We pull and clear/blow the broil orifice and burner ports BEFORE condemning anything; replacing a perfectly good 065650-000 igniter or PB010084 valve on a blocked orifice strands the customer and the broiler still won't light.
• When a gas Viking broiler glows strong and the igniter amp-draws in spec (065650-000 pulling its rated ~3.2-3.6A) but the broil burner still never lights AND the orifice is clear, the fault moves off the igniter to the oven gas safety valve - the dual valve PB010084 (replaces AP5315381 / 810968). The Viking dual valve carries a bake coil and a broil coil; the igniter and valve are wired in series, so the igniter's current is what heats the valve bimetal to open it, but a valve whose BROIL coil has gone open or out-of-spec never opens behind even a healthy igniter, leaving bake working and broil dead. PB010084 is the documented valve for all non-DSI Viking ignition systems except the VGR classic line, so we confirm the model/serial first. Viking valves rarely fail next to weak igniters, so we meter the broil coil and only replace PB010084 after the igniter has tested good on current draw and the orifice is proven clear - never as a first guess.
• On a gas Viking broiler that sparks-and-clicks but won't establish a flame (versus a glow-bar that won't open the valve), the suspect is the broil ignition electrode / spark probe PB040171 (replaces AP5315631 / 811303), the spark electrode that sits in the broil-burner assembly. A cracked ceramic, a fouled tip, or moisture/spillover lets the spark jump to ground so it clicks without lighting the broil burner. We clean and dry the electrode tip, verify its gap to the burner, and clear the broil ports before condemning PB040171 - and we keep this spark-ignition electrode strictly separate from the 065650-000 glow-bar igniter, because Viking uses different ignition hardware (DSI spark vs glow-bar) across its oven generations and ordering the wrong style strands a second truck roll.
• On an ELECTRIC or DUAL-FUEL Viking oven (VDSC dual-fuel, DESO/VESO/VEDO electric) the broiler-not-working signature is an open-circuit upper broil element while bake still heats - a completely different part book from the gas ovens above. The Viking broil element is PJ010001 (240V, AP5317239) on the common fitment, supplied as the broil element assembly PJ010049 (AP5317256) on others; both are SEPARATE parts from the bake element, so we never quote a bake number on a broil-only fault. We pull and meter the broil element at its two terminals at the top of the cavity: a visible blister/break in the loop or an open/'OL' reading condemns it. We run broil and bake separately - broil dead with bake fine isolates to the PJ010001/PJ010049 element, not the control.
• When BOTH broil and the broil-side functions (broil + self-clean) are dead on a dual-fuel Viking but bake heats fine, the fault moves off the PJ010001 element and onto the broil relay on the oven control board. The broil relay is the common component between the broil and clean modes, so a relay that won't close to feed the broil element means a known-good PJ010001 still won't glow and the meter shows no 240V at the element legs during a broil call - a commonly-suspected failure point on these heat-stressed boards. We confirm 240V reaches the element block and that the PJ010001/PJ010049 element tests good before quoting the model-coded control board - on the pre-Middleby (pre-2013) electronics the board is the costly part, so we condemn it last, never before the cheaper element is cleared.
• A charred/discoloured broil-element terminal with a melted lead end is a connection failure, not a dead element, on electric/dual-fuel Viking ovens. The broil unit is the highest-current connection in the cavity, so heat-cycling loosens the push-on spade, resistance rises, and the terminal burns. The correct fix is to re-terminate the burnt broil lead with a high-temp ceramic splice (or the element block confirmed off the rating plate) AND replace the element - a new PJ010001 pushed onto a charred connection just re-burns. We inspect BOTH broil terminals for char before condemning the element; when one is burnt we replace both the element and the burnt terminal/lead together.

Viking broiler not working in Toronto — the local specifics

• The recurring Viking-in-Toronto broiler pattern is two-headed and we triage to it on the phone. On the gas ovens (VGIC/VGSC) the call is overwhelmingly a weak 065650-000 glow-bar igniter that still glows but no longer pulls 3.2-3.6A to open the broil side of the valve - and a stubborn minority where the igniter and PB010084 valve both test good but a grease-plugged broil orifice is the real culprit, the fault that fools a parts-swap. On the dual-fuel/electric ovens (VDSC/DESO) it is an open PJ010001/PJ010049 broil element with bake still fine, or the broil relay on the control board failing to feed a good element. We routinely see bake-works/broil-dead Vikings where a generalist already replaced the wrong part because they never split the gas-vs-electric broil path.
• We bring the 065650-000 igniter, the PB040171 broil spark electrode, and the PJ010001 broil element to these Toronto calls, plus a clamp meter to confirm igniter amp-draw and a kit to clear a clogged broil orifice before condemning anything. The PB010084 dual safety valve and any model-coded oven control board are serial-confirmed and ordered through the distributor/Viking dealer channel - we don't carry them speculatively, because on Viking broiler calls the igniter, orifice or element is the fix far more often than the valve or board.
